WebThe model output indicates: log odds (animal detected time on site) = -1.49644 + 0.21705 * minutes animal on site. To convert to odds ratios, we exponentiate the coefficients: odds (animal detected) = exp (-1.49644) * exp (0.21705 * minutes animal on site) Therefore, the odds and probability of detection if the animal spends 0 minutes on site ... WebCase 1: k = e, i.e. natural log transformed independent variable. Then if β is close to zero we can say "a 1% increase in x leads to a β percent increase in the odds of the outcome." Details follow. The model is. l n ( p / ( 1 − p)) = β 0 + β l n ( x) where l n () is the natural log. WebIf we do the same thing for females, we get 35/74 = .47297297. To get the odds ratio, which is the ratio of the two odds that we have just calculated, we get .47297297/.24657534 = 1.9181682.
